Lattice MARS
Persistent monitoring for asset integrity, flow assurance and digital twins
Lattice MARS provides asset integrity and flow-assurance information from fixed and floating offshore energy infrastructure.
Installed Lattice devices monitor movement, loading and operating conditions while the asset is in service. They process measurements subsea and return information to help operators calibrate digital twins, plan inspections and assess maintenance and life extension.
Information is returned through a fixed gateway using magnetic communications or a combination of acoustic and magnetic links. The communications arrangement is selected for the water depth, asset layout and required frequency of updates.
Applications — fixed-bottom and floating offshore wind; FPSOs; moorings; risers; dynamic cables; pipelines and flowlines; substations; cable protection systems; touchdown zones; and submerged marine hoses.
What it measures — motion, vibration, angle, bending, fatigue, cable and CPS movement, mooring and riser response, pipeline and flowline movement, the position and shape of submerged hoses, temperature, pressure, corrosion / CP and flow behaviour.
Customer value — a measured operating history between campaigns; changes from the installed baseline; calibrated digital twins and engineering models; better inspection priorities; earlier warning of abnormal behaviour; and evidence to proceed, inspect, intervene or defer.
OIS supplies the monitoring system, integration and ongoing support. Information services, reporting, maintenance and upgrades are agreed for each project.
WHAT IT MONITORS
Motion, vibration, inclination, curvature, fatigue, corrosion, pressure, temperature, pipe walking, and other key parameters.
Asset-mounted Lattice devices analyse sensor records subsea and return concise information through the chosen magnetic or combined acoustic-magnetic link.
Operators see how the asset behaved between inspections, keep digital twins and engineering models calibrated, and make better-informed life-extension decisions.
Cable protection monitoring
Lattice devices installed on a cable protection system monitor its movement and response to loading. Measurements support assessment of bending and fatigue, with water-current monitoring added where required. Information is returned through a fixed gateway to support inspection planning and digital-twin calibration.
What this configuration monitors
- CPS movement and bending
- Inclination and curvature
- Water currents
- Vibration and fatigue response
- Temperature and pressure where configured
- Abnormal dynamic events
Each system is configured for the asset, with sensors, battery capacity, measurement frequency and communications selected to meet the monitoring requirements.
